A few issues with my 90 XJ

[poomero]

1st problem is my gas mileage went to hell after i just changed my TPS. What can cause this?

2nd problem is i get speed wobbles when my speedo hits about 55mgh. any ideas on what can be going on? I have a 3 inch lift and i have done the transfer case drop kit already.

3rd problem is when i go over a bump something feels like it is loose and is whacking the bottom of the jeep. i have looked a few times and everything is tight and when i pull on and try to move stuff around i cant find any movement.

Any help on any of this stuff would be great thanks guys.

Try looking at your trac bar, have someone work the steering wheel back and fourth then look under the Jeep for any movement in the tie rods, trac bar etc...as for the TPS make sure to get the voltage set right then disconnect the battery to clear the computer and after 10 minutes reconnect it. Like I said i can help you some time next week. My family is in town so I'll be busy till Easter.

3rd problem:
recheck trackbar bracket and not jsut the tre.
check control arms
check exhaust
hub bolts
u joints
to start
my guess is trackbar bolts are loose
or trackbar is shot

2nd prob
i would almost guarantee that prob 2 is related to problem 3
fix 3 and prob fix 2

prob1
did you adjsut the tps correctly??????
how about swapping in new plugs, wires, and cap and rotor?
all can be had from napa auto for under a total 35$

I will check the trackbar tomorrow and let you guys know.

I did the cap, rotor, plugs and wires about 6 months ago.

I think i adjusted it right but i dont know for sure. i followed one of the right ups on here. i will re check it and see this weekend.
